Having thus described my invention,

Patent, is".:- 1. A sewing. machine including in combination, 'a work support, means for crimping the fabricina direction transversely of thev line of feed, l'stitch-'forming mechanism including a 'needle mounted abovev the Work support and reciprocatingback and forth ina linev at an angle to a vvertical plane, cutting the line `of feed atright angl-es, Whereby the needle is caused toenter the crimped fabric and emerge on the same face of the lfabric, a feeding mechanism including a feed dog 'adapted to engagey the material at the stitching point both in advance and in rear; 45v

of .said crimping means, means for raising 'and lowering said feed dog, and means for moving'said `feed dog back and' forth.

2. A sewing machine including in combi? nation, a Work support having a crimping rib extending substantially'at .right angles' to the line of feed, said crimpingfrib-having slots for the feed dog formed therein, a lfeeding mechanism includinga feed dog adaptedI to extend through said feed slots and engage'the material at thecrimp therein, means for raising andlovvering said feed dog., means for moving said feed dog back and forth, .and stitch-forming mechanism including a needle mounted above the Work support and reciprocating back and forth substantially7 in the line of feed, said needle being so disposed asto enter the material in the,direction of feed of the fabrics.

3. A blind stitch sewingmachine having may or may notcarry aV thread and is' pass onlythrough the bases of thev what Iclaim and desire to secure by Lettersstitch-,forming nie'chanism,l including av and emerging from the same face o'f the fabric, alooper coperating therewith to form stitches, means for crimping the Work, and a ruliling device; substantially as described.

5 A sewing andruling lmachiiie,.fem bodyinga feedingmechanism. aivork support, a needle entering and emerging-on the same face of the fabric, and means for reciprocating it so that said needle enters the fabric substantially in the line andy in the direction of ,the feed. a looper cooperating tliereivitli to form stitches, and a ruiiiing device, whereby a,fabric1`na v be ruiied and the ruflies secured by stitches' passing througl'i the bases only of the rui'les; substantially .as described.

Ablind stitch sewi'ng machine, embodying a feed-ing mechanism, a worl support, a needle entering and emeigingon the same face of the fabric, means'for'reciproeating it so that said needle enters the -fabric substantiallv in theI line and in the direction of the feed. a looper cooperating there# ivith'to foim stitches. both said needle and looper being arranged and operating above the Work support, a ruflling device, 'means for operating ythe Same, and means -for crimping the goodstransversely of the di- Irection-of feedisubstantially as described.

7. A blind stitchsewing machine, embodying a lfeeding mechanism. a ivorl; support, a needle entering and emerging on the same face of the fabric, means for reciprocating it so that said needle entersl 'the fabric substantially' in the line and in the direction of the feed. a looner Coiiierating therewith to form stitches. both said needle and loooer being arranged and operating above the Work support, a ruiiing device, means for operatingthe same. means for adiusting the throw of the ruiling device, and means for'crimpingthe goods transverselv of the feed; substantially vas d escribed.

8. 'The combination with a Work support, a ruiiiing blade,- means for operating said ruiiing blade, and stitch-forming mechanism including a needlel moving subsianln testimony whereof l aflx my. signature, tially in a line parallel with the movements in presence of two Witnesses. of the rullling blade, and in the same direc- `tion therewitha whereby the fabric gathered LANSXNG Om DERDONK' .5 by the milling blade .is entered by said W'itnesses:

needle, and the needle emerges on the same A. A. MERRITT,
